Specification of Letters Patent.

Patented June 1, 1909.

Application filed January 2, 1908. Serial No. 409,022.

To alt 'WfiOHt it ow/y concern:

Be it known that I, Wrmmna. 1 Res woniin'of Brockton, in the county of Plymouth and State of ivfassachusetts, have invented certain new and useful improve: ments in Machines forjnsscmbling Heel-Lift Sections, of which the following is a specification.

This invention has for its object to provide a machine for quickly and conveniently assembling andv pressing together the parts of the compound heel lift shown in Letters Patent of the United States No. 867,909, granted to William F. Bostock, October S, 1907. The said heel lift is composed of two general parts, via, a pieced lift made up of pieces or sections which are abutted together edge to edge and form a lift body, and a thin continuous connecting lift which is placed upon and covers one side of the pieced lift, the said parts being united. by cement interposed between the abutting edges of the sections of the pieced lift and between the inner side of the connecting lift and the corresponding side of the pieced lift.

To these ends my invention. consists in the construct-hm and combination of parts substantially hereinafter described and claimed.

Of the armompsmying d ran-ings forming a part of this specification, Figure l represents a top plan View of a machine embodying my invention. Fig. 2 represents a section on line 2- 2 of Fig. 1. Fig. 3 represents a section on line 3-3 of l ig. 1 Fig. lrepresents a perspective View showing the pieced lift and the connecting lift, the said parts being represented by full lines as separated from. each other, and by full and dotted lines assembled.

'lhc same letters of refcrcm-e indicate the same parts in all the figures.

A machine embodying my .ovoulion as here shown includes a circular tabh- (/1 which is preferably of annular form and is supported by arms I) radiating from a central hub c, which is mounted to rotate freely on a vertical spindle or bearing d having a collar or enlargement d at its lower portionwhich supports the weight of the carrier. .111 this embodiment of the invention certain portions of the table a, rim; those portions which are partially bounded by the fixed gates a e constitute beds (1 adapted to support the scctionsf f of the pieced lift or lift body. it

i is obvious however that the beds a may be made mseparate parts or'pieces secured in any suitable way to the carrier.

Each bed a and the accompanying gages c c constitute a part of an organism for acting on a single compound lift, the other parts of the organism being as follows :-g represents an edge presser which is movable over the bed a" and in direction substantially parallel therewith toward and from the gages e c, the presscr 9 being normally forced by spring pressure toward said gages, the arrangement being such that when the lift scctionsff are placed upon the bed a between the gage c and the edge presser 9, this being permitted by tho retraction of the the edge prcsser vill force thcpicced lift to-- ward the c and thus press the adjacent edges of the sections ff closely together. Said edges are coated with cement before they are placed on the bed, and the operator in applying. them to the bed presses their rear ends against the gage c. He then re leases the prcsser g, the latterpressing one side edge of the pieced lift against the gage c.

72, represents a presser foot which is movable toward and from the bed a and is adapt ed to cover the thin connecting liftf said lift having been. deposited by the operator upon the scctiom f after the latter have been positioned between the gages a c and the edge prcsscr g. The upper sirfaces of the necting layer f or all of these surfaces, are coated with cement, so that when the prcsscr foot is brought down upon the coi'mecting liftf it causes the adhcsioi'l of the latter to the sections ff. 'lhe prcsscr foot 7t is provided with a resilient shank 7t which is preferably a curved strip of spring steel. Said shank is movable cndwiso andv is guided or controlled in its movc'nurnts by guides 't i which are rigidly allixed to the carrier, said guides bein preferably the forked ends of a standard attached to the carrier. The guide i has a slot i through which the shank i It passes. 'ihe guide 'i has a recess i, the bottom of said recess forming a bearing for the shank, while the sides of the recess guide the shank in its movements.

(then the presscr foot and shank are moved to the position shown in Fig. 3, the shank is put under tension by its bearing on I the bottom of the recess i and on the upper edge presser against the force of its spring,

sectionsff or the under surfaze of the con- Fig. 3, and by full lines at the lower portion of Flg. 1.

The gages e e are preferably adjustably secured by means of screws 7c, the gage e having a slot e which permits longitudinal adu'stment of the gage e. The gage e is ada ted to swing on its confining screw when the atter is loosened, so that said gage may be moved laterally over the bed. The edge resser g is here shown as mounted on the rec end of a resilient arm g, which is su' ported by a screw 9 said arm g normally tending to force the edge resser 9 toward the gages e e. If desired t e spring arms 9 of two adjacent edge pressers 9 may be made in one piece, having convolutions g wound about two adjacent screws 9 and a connectlng portion 9 between said screws. convolutions g are free to expand and contract, and form a part of the spring which acts on the edge presser 9'.

From the foregoingand by reference to the drawing, it will be seen that the machine may be operated as follows: The operator stand ing at one side of the machine andat a point which may be considered the front of the ma- ;chine, brings each of the described organlsms successively to the point where he is located, by suitably moving the carrier. Assuming that all the organisms are charged with compound lift parts f f and f the operator removes the compound lift which has been for a sufficient length of time under pressure, and then while holding the edge presser g in a retracted position, places the Sections of the pieced lift on the bed with the back edge of the pieced lift bearing against the gage c. He then releases the edge presser g, and the latter bearsagainst tie opposite side edge of the pieced lift, and forces the latter toward the gage e. The pressure thus applied to the pieced lift is suihcient to force the'abutting edges of the sections together. The operator then a plies the connecting lift f to the upper si e of the pieced lift, and then moves the presser foot h downwardly upon the connecting lift, so that the latter is held with sufficient pressure against the pieced lift. The operator then gives a partial movement to the carrier, bringlng another completely pressed lift to the operating station, where the same opera.- tion ,is repeated. The parts of each compound lift after being assembled as above described, remain under pressure during a com lete rotation of the carrier, so that time is a. orded for the setting of the cement, the
